I thought I'd start a thread for the new V2 board.

Apart from a different user USB socket, the first problem I've encountered is getting the user USB port working.

There is no green LED or any led lit for the port.

There is therefore no supply rail at the port.

I've gone through the links and think I've got them correct, here is what I've set up.


SB52 OFF Vbat from external backup source.

Ethernet PHY FREES UP

SB29 OFF PC5
SB30 OFF PG13
SB27 OFF PG11

SB36 OFF PC4
SB72 OFF PA2
SB64 OFF PC1
SB57 OFF PA1

JP6 OFF PB13
SB32 OFF PA7

SB76 OFF PG7

SB24 OFF USB ID PA10
SB23 OFF USB vBus not connected to PA9


The Board itself is running fine apart from the User USB problem. I can't find a circuit for the new board so I can't test/verify control voltages to the power control switch for the user USB port.
